2014 Transmission Updates
If you compare 2013 and 2014 transmissions on one of the OEM parts websites, you can see that Honda changed the part numbers for three parts (mainshaft gear 2/3, 4, and 5) in 2014. Somewhere on the web I saw photos comparing the old and new parts. Honda clearly knew they had a problem, though from what I've read it's pretty rare, like the rear brake issue.
I've only heard of a few reports where the ghost shifting actually caused damage. Those cases were bent shift forks.
